Adjustable elevated light for transportation vehicles

ABSTRACT

An adjustable, elevated and externally mounted lighting device ( 21 ) for vehicles such as school busses ( 22 ) and other types of vehicles, that provides a pool of light ( 23 ) to passenger loading and unloading areas for better visibility of passengers, vehicle drivers, and other vehicle operators in the vicinity during hours of darkness. The light&#39;s adjustability, combined with a diffused lens ( 29 ), provides a broad and bright pool of light ( 23 ) without obstructing passenger visibility or driver use of side mirrors ( 30 ). The light ( 21 ) is connected to the vehicle&#39;s on-board electrical power system and is activated automatically without distracting driver attentiveness, but with provisions for manual over-ride activation if needed in special circumstances such as emergencies or wheelchair loading/unloading.

BACKGROUND—FIELD OF INVENTION

This invention relates to providing adjustable, elevated and externally mounted diffused illumination of the loading and unloading areas adjacent to a vehicle, such as needed for school/public transportation busses & delivery trucks. This is accomplished by creating an adjustable lighting system utilizing adjustable mounting brackets and adjustable interior and exterior mounting equipment; together with electric light source & diffused lighting lens.

BACKGROUND—DESCRIPTION OF PRIOR ART

Transportation of people and goods occurs not only during daylight but also during the hours of darkness and in inclement weather. In many areas the absence of sufficient ambient light (e.g. street lamps), makes loading and unloading the vehicle a particularly hazardous procedure, especially for small school children. Exiting a vehicle without proper light can entail stepping out into the dark where snow, ice, rocks, tree limbs, and other hazards cannot be seen.

Most rural locations have no ambient light sources and are dangerous during dark hours pick-ups and drop-offs, which is very common in the Northern latitudes. School districts at all latitudes have at least some nighttime extra-curricular activities as well. These include sports and field trips that can benefit from improved area lighting.

There are several ways in which original equipment manufacturers and after-market suppliers have addressed the concept of both interior and exterior vehicle lighting. None, however, provide diffused elevated light to passenger waiting areas prior to stopping, during the loading/unloading, and after the doors have closed.

U.S. Pat. No. 5,467,071 Koenig does not provide overhead lighting for loading and unloading passengers to see by and for driver's visibility of this activity without creating mirror glare.

U.S. Pat. No. 4,964,022 Lane also does not provide adjustable and diffused lighting to enable safe visibility for passengers while avoiding blinding the driver with glare in the mirrors.

Likewise, U.S. Pat. No. 2,065,876 Siegfreid does not provide for adjustable and diffused lighting that enables safe visibility for passengers while not blinding driver views with glare in the mirrors.

U.S. Pat. No. 1,072,096 Dean also does not provide diffused and adjustable lighting that enables safe visibility for passengers while not blinding driver views with glare in the mirrors.

Existing interior lighting on or above the stairway(s), around the driver, and in other portions of the vehicle exist for the purpose of providing better on-board visibility inside the vehicle. None of these interior designs or applications provides adequate light to the passenger waiting areas.

Similarly, exterior lighting on vehicles including but not limited to headlights, taillights, running lights, and warning lights are not designed to, nor do they provide, sufficient light by which both passengers and drivers can safely see the loading and unloading environment.

SUMMARY

In accordance with the present invention, an adjustable, elevated, externally mounted lighting device that provides illumination by means of a control switch within a vehicle to substantially enhance the level of light in the loading and unloading areas.

OBJECTS AND ADVANTAGES

Accordingly, increased light levels in the passenger waiting areas afford the following advantages:

-   -   (a) enhances safety of passengers while loading and unloading by         reducing the risk of a trip or fall     -   (b) improves driver visibility of both hazards and passengers         when pulling to a stop, without creating glare in the mirrors.     -   (c) improves driver visibility of passenger waiting areas         ensuring appropriate clearance when pulling away     -   (d) provides drivers of other vehicles approaching the stopped         vehicle with improved visibility of the environment immediately         surrounding the stopped vehicle     -   (e) enhances safety of driver while loading and unloading goods         by reducing the risk of a trip or fall         Further objects and advantages of my invention will become         apparent from a consideration of the drawings and ensuing         description.
